L'embonpoint des voitures

How Cars Are Getting Fatter
Spiky-headed weight-loss guru Susan Powter once pleaded with the country's overfed citizens to "stop the insanity." Some heeded her advice (Kelly Osbourne), some didn't (David Anthony Higgins; anyone who's eaten multiple KFC Double Downs). The auto industry didn't either.

Tightening safety regulations, feature bloat and heightened demand for cars that consumers perceive to be safer (i.e., larger ones) have led to the enfattening of automobiles over three decades. These larger, heavier cars have amassed tremendous technical complexity, much of which has gone toward managing the physical stresses of size while retaining a semblance of fuel efficiency.

Toyota Corolla

In thirty years, the Toyota Corolla progressed from a sprightly, "Oh, What a Feeling" econobox to a staid interstate cruiser. A full-grown sedan-in-a-blanket, if you will.


Edmunds.com reports small (i.e., compact) cars now weigh, on average, 549 pounds more, have 61 more horsepower and have a 6.4-inch longer wheelbase than they did in 1990. So, where small cars once were indeed small, they are now larger. But since they're smaller than larger cars, they are still, by definition, small. (Immanuel Kant, call the front desk.)

Actually, car size isn't quite so relativist as all that. According to the U.S. government, it's interior size that determines whether a car is classified as big or small, which is how you end up with the Rolls-Royce in the same class as a Honda Civic, and why cars get bigger yet never change their definition.

Honda Accord

The Honda Accord sedan was more comfortable and sporty than its smallish rivals when it arrived on the scene three decades ago. Now it's in the same class as the Ford Crown Vic!


The major culprit in cars' expanding waistlines is indeed safety specs—better side-impact protection, more robust crumple zones and taller front ends designed to protect the lives of people who've wandered into busy streets. In essence, we've traded agility for safety and comfort, which in most cases has resulted in a dampening of that "driving feel" you grew up reading about.

To be fair, automakers have been trying hard to shed weight, and rumors persist that Ford may even consider a magnesium frame for the next F-150, likely cutting out hundreds of pounds. Yet, none has yet been able to offset the bloat.

There is some good news. According to Edmunds, small cars now get 2.5 more miles per gallon in combined fuel economy estimates since 1990 by way of advancements in engine technology, even with all the extra power needed to move them along.

Ford F-150

The ubiquitous Ford pickup shrank considerably after the gas shocks of the 1970s. But after that it ballooned into the masonite-hauling behemoth we have today.


It's not just small cars that have burst out of their shorts. Midsize cars and pickup trucks have also exhibited serial widening and increased gravitational pull over the past three decades.

Will the bloat continue on into the next decade? We're betting the safety curve will eventually level out, leaving less finagling for regulators to do. Plus, as lighter, stronger materials become cheaper to produce (with some help from supercar buyers, and the defense and aerospace industries), we'll finally see some dramatic weight reduction, which will affect the development of all the rest of cars' systems. If not, the Jabba the Hut Edition F-150 may end up clogging your driveway.

Coudonc, à part ton gros Buick Regal, y'as tu quelque chose pour toi qui est pas de la marde?

Euh,quel âge as-tu?Parce que non,les petits véhicules,ce n'est pas de la merde.À chacun ces goûts,selon son budget.Ton commentaire frôle le ridicule.

C'est pas juste une question de budget.. Et oui ca frôle le ridicule!

Évidemment que non,ce n'est pas juste une question de budget parce que,comme plusieurs aiment le mentionner,une sous-compacte avec plusieurs options peux coûter le même prix qu'une compacte.Ce que je voulais dire,c'est que choisir une sous-compacte n'est pas seulement une question de $$$ mais bien de goût personnel,en plus que majoritairement,lorsqu'on choisie bien la version,elle peut être moins chère qu'une voiture de catégorie dite supérieure.

Des fois je me demande si il y en a qui se rappellent que,celui qui paye une auto,c'est l'acheteur..

Et à part ca?

Excellent article mais le sujet est très très très complexe... le monde veulent avoir des char sécuritaire, donc ça prend de la tole, il veule des chars accessible, donc de la tôle d'acier et non d'alu... en plus, le monde sont de plus en plus gros, pas juste ici, en europe aussi donc ça prend des chars avec de la place, donc de long empattement mais des chassis de béton pour combiner. Sans parler encore des progrès en terme de tenue de route et de stabilité routière...

Les voitures du moment sont des merveilles d'engineering et celles de demain seront encore plus écoeurante. Audi a dit que la prochaine gen de A4 serait de 400 livres plus légère. j'ai hâte de voir...
